I have seen 1 or two answers to this, but none of them have had a comprehensive list of ALL of the backup methods on this list and what each of them is used for and the similarities and differences between all of them. I'm asking for what these things do and why you would use one over the other.
Here's what I've gathered so far.
File History: Saves older copies of files
Backup and Restore: ??
System Image: Complete clone of the hard disk put into a file
System Protection (Restore Points): used to roll back files.
